Unusual bipolar behavior was observed with D-pi-D, displaying the redox property similar to that of D-pi-A. Single-layer lightemitting (LE) devices fabricated with such electronically dissimilar oligomers exhibited a close resemblance in their diode characteristics that are commonly observed with bipolar LE materials.
